  • the system can automatically adjust the output voltage according to the resistance of the coil, thereby preventing a short-circuit effect from being generated in the coil.
  • the user can select a desired output mode according to need, and also can select a desired output mode by switching between the output modes during smoking, there increasing the diversity of options.
  • the user experience and the quality of the electronic cigarette can be improved.
  • FIGS. 1-2 illustrate a method and a system for controlling an electronic cigarette with multiple output modes.
  • the method for controlling the electronic cigarette with multiple output modes comprises following steps.
  • step 1 a first controller U1 determines whether button signals are input for N times when the system is powered on.
  • step 2 if a determination result of step 1 is yes, the system enters a locked state. Only when the system is under a locked state can switching between the output modes be implemented. A user is not allowed to smoke the electronic cigarette when the system is in the locked state, that is, smoking is separated from the output modes to avoid incorrect operations.
  • the first controller U1 determines whether a switch signal for switching between the output modes is input to the first controller U1 via a button K under the locked state.
  • the output modes comprise a voltage output mode and a power output mode which can be stored in a memory of the first controller U1.
  • the first controller U1 determines that the button K inputs a correct switch signal when the button K is pressed for a time period greater than or equal to A seconds.
  • step 4 if a determination result of step 3 is yes, the first controller U1 switches from a current output mode to a new output mode and stores the new output mode in the memory. Under the locked state, if the button K is pressed for a time period greater than or equal to A seconds, the first controller U1 determines that the button K inputs the switch signal for switching between the output modes. Then, the first controller U1 varies the output mode stored in the memory, that is, the first controller U1 switches from the current output mode to the new output mode. For example, when the system is powered on, the output mode stored in the first controller U1 is the voltage output mode. After the switch signal is input, the first controller U1 varies the stored output mode to the power output mode.
  • the first controller U1 controls outputs according to the stored output mode in step 4.
  • Each of the voltage output mode and the power output mode corresponds to one light emitting diode (LED).
  • the first controller U1 controls one of the two LEDs to emit light to indicate a current output mode.
  • the electronic cigarette comprises a symbolic identifier "VV" corresponding to the voltage output mode.
  • the symbolic identifier "VV” further corresponds to one LED. If the LED corresponding to the symbolic identifier "VV" emits light, it indicates that the current output mode is the voltage output mode.
  • the electronic cigarette further comprises a symbolic identifier "VW" corresponding to the power output mode.
  • the symbolic identifier "VW” corresponds to another LED. If the LED corresponding to the symbolic identifier "VW” emits light, it indicates that the current output mode is the power output mode. The user can intuitively select a desired output mode according to the indication from the two LEDs.
  • step 5 if a determination result of step 3 is no, the first controller U1 detects and determines whether button signals are input for M times. If no, the procedure goes back to step 3. If yes, the system is unlocked. After step 4, the procedure also goes to step 5, and whether an unlocked signal is input by the user is determined. After the system is unlocked, the user can smoke the electronic cigarette by operating the button K.
  • the method further comprises following steps. If a determination result of step 1 is no (that is, if the button signal from the button K is not for locking the system), the procedure goes to step 6. Similarly, after the system is unlocked in step 5, the procedure also goes to step 6, and the first controller U1 detects and determines whether a smoking signal is input. That is, the first controller U1 determines whether the user keeps pressing the button K to transmit the smoking signal to the first controller U1 under the unlocked state. If no, the system enters a low power consumption state. If yes, the procedure goes to step 7, and the first controller U1 generates a control signal according to a detection signal from a second controller U2. The detection signal from the second controller U2 comprises a voltage adjusting signal manually input by the user.
  • the first controller U1 controls outputs according to the voltage preset by the user.
  • the memory of the first controller U1 stores two output modes comprising the voltage output mode and the power output mode.
  • the output voltage is constant when the voltage output mode is selected and stored. Only when the user inputs a voltage adjusting signal, can the output voltage can varied according to the voltage preset by the user. For example, a current output voltage is 4V. When the user inputs a voltage adjusting signal of 3.5V, the output voltage varies from 4V to 3.5 V.
  • the power output mode the output power is constant and depends on the output voltage.
  • the output power can be varied by adjusting the output voltage. That is, if the user inputs a voltage adjusting signal, the output power can be varied according to the voltage preset by the user. For example, a current output power is 4W. When the user inputs a power adjusting signal of 3.5W, the output power changes from 4W to 3.5 W.
  • the detection signal from the second controller U2 may also comprise a voltage sample signal for sampling a voltage of the battery B.
  • the second controller U2 transforms the voltage sample signal to an actual battery voltage, and transmits the actual battery voltage to the first controller U1.
  • the first controller U1 determines whether the actual battery voltage is high enough to heat a coil which is configured to heat the liquid solution.
  • the battery B is electrically connected to the second controller U2.
  • the second controller U2 is electrically connected to a voltage comparator Q1.
  • the voltage comparator Q1 provides the second controller U2 with a standard voltage.
  • the second controller U2 compares the battery voltage with the standard voltage provided by the voltage comparator Q1, and determines the actual battery voltage of the battery B. If the first controller U1 determines that the actual battery voltage is high enough to heat the coil, the first controller U1 controls the LED corresponding to the current output mode to emit light with a breathing frequency to indicate the current power of the battery B. The less the breathing frequency of the LED, the higher the current power of the battery B. Otherwise, the current power of the battery B will be exhausted. When the current battery voltage is less than or equal to 3.3V, the first controller U1 stops outputting.
  • the method according to the present disclosure is not limited thereto, and can further comprise following steps.
  • the first controller U1 determines whether the USB connector is connected to a charger after the system is powered on. If yes, the system enters a charging state.

That is, the second controller U2 detects whether the coil is in a short circuit condition, or whether a resistance of the coil is too low. If the coil breaks down, the first controller U1 stops outputting. During smoking, if a time period for pressing the button K is greater than P seconds (P can be "10" or other numbers), the first controller U1 stops outputting, and further generates a warning signal to warn the user, thereby protecting the coil from being damaged.
